I have a loaded vision impulse for sale:
The Vision Impulse has the gas through grip and horizontal regulator blue light vision cricket board. Upgrades include drop, tapeworm, delrin bolt, light weight hammer assembly, blade trigger, dye stickies, 10" Custom Products barrel, and 12" Progressive barrel. There may be a few other upgrades I am forgetting. $400 shipped.
Regarding a tank, I have 48/3000 tank that needs to have the regulator rebuilt. I will throw it in for an extra $25 (that includes shipping). I have contacted local stores and the manufacturer and have been told it is a $20 fix. If you are experienced in tank regulators, you may be able to rebuild it yourself.
